Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 26, 1907. Serial No. 359,503.

To all whom it may concern:

Be it known that 1, Lines P. POOL, a citizen of the United States,residing in the borough of Brooklyn, in the county of Kings, city andState of New York, have invented certain new and useful Improvements inN avigable Vessels, of which the following is a specification.

This invention relates to navigable vessels, and it has for its objectto provide vessels of the character described of improved stability intheir course throughor upon the supporting element, whereby and whereinthe customary careenings, gyrations and oscillations of such vessels asat present constructed may be substantially overcome.

In carrying out the invention I provide a supporting member which restsdirectly upon or moves through the supporting medium; a load carryingmember independent of but connected with the supporting member andcapable of movement relative to the supporting member; and a ballast orcounterpoise member which is operatively connected with the loadcarrying member in such manner that it shall execute movementssimultaneously with those of the load carrying member and such as shallcompensate for the careenings, gyrations and oscillations of said loadcarrying member due to the unstable support of the load carrying memberby the supporting member in the supporting medium.

In the drawing: Figure l is a side elevation partly in section of asailing vessel constructed according to the invention. Fig. 2 is avertical transverse sectional view of the same, taken upon the line X-X,Fig. 1 and looking in the direction of the appended arrow, the partsbeing shown in full lines in the normal relative positions, and indotted lines in the position assumed according to the novel constructionand operative connection of parts.

Corresponding parts in all the figures are denoted by the same referencecharacters.

Referring with particularity to the drawing, the vessel comprises asupporting member or hull A, a load carrying member or deck B, carryingthe propelling sail elements C, a ballast member D carried by the hull Aand movable laterally with relation thereto, and operative connections Ebetween the deck B the ballast member D and the hull A. The deck B ismovably connected with the hull A and mounted to oscillate laterallyupon a central longitudinal pivot line. The ballast member D is arrangedsubstantially centrally of the hull A which is preferably cut away, asat F, to form a forward hull portion A and an aft hull portion A betweenwhich the ballast member D is disposed and depends as a keel.

A preferred form of construction and connection of parts and members isas follows: he hull portions A and A carry, and are'connected rigidlytogether, by a shaft or beam 1 which extends longitudinally of thevessel and bridges the cut away portion or space between the hullportions A and A as at 2. The deck B is supported directly upon and tiedto the shaft 1 by bearings 3, which, with proper conformation of thelower portion of the deck and the upper portion of the hull, permit thedeck to oscillate laterally in both directions with the shaft asa-central longitudinal support. The ballast member or keel D issuspended directly from the shaft 1 by a collar or knuckle 4, at theportion 2 of the shaft, in such manner as to be capable of lateraloscillation, or oscillation in the same plane as the oscillatory planeof the deck B, and its proportioning may be such as to approximatelyextend across and fill the space between .the hull portions A and A Thekeel D may extend below the lowermost portion of the hull A and beweighted at its lower portion, as at 5.

The operative connection E comprises a member E and a member E arrangedat either side of the vessel; the member E being connected with one sideof the hull A, and the corresponding sides of the deck B and keel D, andthe member E being connected with the opposite sides of the hull A deckB and keel D. Each of the members E and E consists of a rope, cable orchain 6 which is connected at one end, as at 7 with the deck B, isconnected at the other end, as at 8, with the hull A, and intermediateof its ends is passed about a pulley block 9 secured to the keel D atthe upper portion of the latter.

The sail elements 0 may be of any preferred type, and, as shown,comprise a mast 10 stepped in the deck B and stayed to the same, as at11, and a sail proper .12 carried by the mast. I

The operation of a vessel constructed as described will be manifest fromthe foregoing description taken in connection with the accompanyingdrawing and the following statement. Normally the parts and members, insailing, occupy the relative positions shown in full lines in Figs. 1and 2, with the deck B extending in a horizontal plane and the keel Ddepending be neath the deck in a vertical plane. If, new, anydisturbance of the equilibrium of the deck occurs, causing it tooscillate relative to the hull A, one side of the deck is elevated andthe other side of the deck is depressed; and the cable 6 which isconnected with the elevated side tends to straighten out, and, in doingso, swings the keel D laterally in the direction of the elevated side ofthe deck. The elevation of the side of the deck is thus opposed by theweight of the keel as it is increasingly imposed upon the elevated sideof the deck, the result being ultimate return of the deck, under theweight of the keel, to normal horizontal position. If the weight of thekeel be sufficient, it is manifest that but slight oscillation of thedeck will be permitted; and the points of connection of cables 6 withthe hull, deck and keel may be so relatively disposed that theoscillations of the keel may excel in degrees of an arc thecorrespondingoscillations of the deck, causing an increased balancingpower on the part of the keel over that obtained were the keel connectedWith the deck in fixed angular relation. The normal relativedispositions of the points of connection of each of the cables 6 withthe deck, hull and keel, must, manifestly be other than arrangement in astraight line. As the cable 6 on one side of the vessel tends tostraighten out, because of elevation of the corresponding side of thedeck, the other cable 6 is slackened by the depression of thecorresponding side of the deck, thus permitting the above describedoscillation of the keel.

The invention, while hereinabove described as embodied in a sailingvessel, comprehends broadly any type of navigable vessel comprising asupporting member, a load-carrying member, and a ballast member, thelatter member being movable with relation to the supporting member andoperatively connected with the load-carrying member, and theload-carrying member being movable with relation to the supportingmember. I therefore do not wish to be understood as limiting myself tothe specific construction, relative arrangement and operative connectionof parts herein described and illustrated, but reserve the right to varythe same in adapting the invention to varying conditions of use, Withoutdeparting from the spirit of the invention or the terms of the followingclaims:

Having thus described my invention, I claim and' desire to secure byLetters Patent:
